3/8 + 1/16= 7/16
so it's c. 7/16
If the amount of time taken to go said distance is x and the amount of time taken to go back said distance is y, then the amount of miles total is 7x+3y due to that for every hour, she adds 7 miles when going there and 3 miles for walking back. In addition, since the total amount of time is 4 hours, x+y=4 as the total time spent as well as 7x=3y due to that they're the same distance.
x+y=4
7x=3y
Dividing the second equation by 7, we get x=3y/7. Plugging that into the first equation, we get 3y/7+y=4=10y/7 (since y=7y/7). Multiplying both sides by 7 and then dividing both by 10, we get 28/10=2.8=y in hours. Since 0.1 hours is 60/10=6 minutes, and 0.8/0.1=8, 6*8=48 minutes=0.8 hours, meaning that she should plan to spend 2 hours and 48 minutes walking back
Step-by-step explanation:
The vertex is the point (-4, 7).
Start at (0,84) as your y-intercept because thats what he starts with. Then make a negative slope decreasing by 2 each time the x value is increased by 1
Answer:
Step-by-step explanation:
<em>Set 1:</em> 12, 8, 6, 4, 10,1
Now find mean of 6 and 4:
(6+4)/2=10/2:
5 << answer of set 1
<em>Set 2: </em>6,3,5, 11, 2, 9,5,0
(11+2)/2=6.5
<em>Set 3: </em>30, 16, 49, 25
(16+49)=65/2
32.5
